IMPROVEMENT IN CORN-PLANTERS.

Specification forming part of Letters Patent No. 134,032, dated December17, 1872.

f To all whom it may concern:

ence being had to the" annexed drawing making a part of thisspecification, and to the letters and figures of reference markedthereon.

Figure l of the drawing is a representation of a plan view of myinvention. Fig. 2 is a longitudinal vertical section of the same. Figs.3 and 4 are details.

This invention has relation to that class of corn-planters in which theseed-dropping devices ride upon the shoes which are pivoted to the frontof the main frame; and it consists in the construction and novelarrangement of the concave couplings connecting the front and rearportions of the main frame, whereby the seed-boxes are brought near theground, the dropping-tubes and their valves shortened with a view to anincrease of angular space between the valve and the tubewall, and easeof movement when operated by the seedslide.

In the accompanying drawing, the letter A designates the main frame ofthe corn-planter; B, the wheels; C, the axle; andk D, a pivoted bar atthe rear end of the frame, holding scrapers d, and operated by afoot-lever,

d. The longitudinal bars A of the main frame are made in two parts andunited by concave coupling-plates a, forming notches to receive thetransverse bar of the seedingframe when it descends below the level ofthe frame A. To the forward part of the frame A is pivoted theseeding-frame, consisting of the transverse bar B and arms b. The latterare pivoted to .the ends of the front bar of the main frame. The bar Bvibrates in and over -the concave couplings, and supports the seed-boxesE, the seed-dropping devices, seat e, seed-shoes e1, and adjustableguiding-roller e2. F indicates curved plates secured to the seed-shoesand pivoted to the bar A2. Two of these plates are attached to eachshoe, and, passing forward parallel with each other, are secured by thepivot-pin on each side of the arm b of the seeding-frame. Between thecurved plates of each shoe is pivoted an opening-wheel, Gr. At each endof the bar B', on its upper surface, is secured a plate, c, centrallyrecessed or channeled to receive the end of the seed-slide d. The platec is also slotted at its center for the passage of the seed, and at theside of the channel for the passage of the stud a of the valve z ofthedropping-tube, said stud being connect-ed with said valve by a shankextending horizontallyunder the plates c. This plate is also slotted atits side to permit the passage and play of the arm j' of the slide-ba-r,said arm f bearing on the adjustable forked stop-plate m, whichregulates the size of the seed-openings through the slidebar, and isconnected to the arm f by means of a clamp-screw. Opposite the arm f areplaced, on the slide-bar, two small lugs or projections, o, which extendinto the lateral chamber of the recess of the plate c and elnbrace thestud n of the tube-valve, serving to communicate to said valve thereciproeating motion of the slide-bar, causing the same to vibrateregularly in its tube e1. Underneath the bar B are secured stirrups h',in which are stepped the levers or handles which pass through the saidbar B and the seed-slide, and serve to operate the latter. Each plate cis provided at its corners with upwardly-projecting pins or studs o',which pass through perforations in the flanches d of the seed-boxes,thus securing said boxes in position, and at the same time permittingthem to be easily removed, when necessary, for repairing the seed-slideor other purpose. Each box is provided with a bent plate, under which issecured the seed-brush. Thus the brush is removed from the slide withvthe box, enabling the operator to adjust the stopplate m with facility.The bar B may be raised by means of a lever, H, pivoted to astandard-plate, J1., on the axle, and operated in rear. Underneath thisbar B,'and at the inside of each shoe, is secured an adjustablegage-wheel.
